Ultrasonic Industry terms
What is Ultrasonic wave? Ultrasonic vibration frequency is greater than 20000Hz , and its number of vibrations per second ( frequency ) is very high, beyond the general limit of human hearing (20000Hz), so people can not hear this sound waves. Ultrasonic technology is used in many different fields. Ultrasound machines are used to detect objects and measure distances.In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Ultrasonic imaging (sonography) is used in both veterinary medicine and human medicine. Organisms such as bats and porpoises use ultrasound for locating prey and obstacles. Ultrasound image of a fetus in the womb, viewed at 12 weeks of pregnancy (bidimensional-scan Industrially, ultrasound is used for cleaning and for mixing, and to accelerate chemical processes. Because the ultrasonic wave has high frequency, wave length, and thus spread the good direction, penetrating ability, which is why the design of ultrasonic cleaning machine causes. Within a certain frequency range in the liquid medium ultrasonic cleaning the workpiece can play a role. This cleaning technology since its inception, has been the general concern of all walks of life. The use of ultrasonic cleaning machine greatly improves the efficiency and precision cleaning, ever clean corners, blind holes and difficult to reach filth Department has been to make people feel more headaches, development and application of new technologies to make this work becomes easy. What is the ultrasonic frequency? The inherent vibration frequency is produced by the ultrasonic transducer under the cleaning machine and the frequency selection is general in the range 20-130KHZ.Choosing the best frequency is very important and you need to do some experiments if you want your working frequency is very exactly. We can wash the different parts according to the different frequency but in addition to the ultrasonic frequency ,the ultrasonic sound pressure strength and physical properties of the cleaning medium is also significant such as temperature, vapor pressure, surface tension, density, viscosity, etc. What is ultrasonic transducer? What is Ultrasonic Generator ? Ultrasonic generator can produce a specific frequency signal, this signal can be a sine signal or pulse signal, this particular frequency is also for the ultrasonic transducer.In general, the ultrasonic frequency is 25 KHZ, 28 KHZ, 35 KHZ, 40 KHZ; 100 KHZ. What is Ultrasonic cleaning bath or tank It is used to fill with liquid like water or any solution and mixing with the items you want to clean. there are many different size to fit your items such as 3L, 6L ,10L ,30L and may be have larger capacity in the professional cleaning field Type 304 is the most versatile and widely used stainless steel. most people still sometimes referred to its old name 18/8 ,because its main chemical components including 18% chromium and 8% nickel. In general, we add the power of every ultrasonic transducer togather to caculate the ultrasonic cleaning system.so we can say the ultrasonic transducers supply the ultrasonic energy. what is cavitation effict? Ultrasonic vibration propagation of sound waves in the liquid reaches an atmospheric pressure, its power density is 0.35w/C㎡, when the ultrasonic sound waves can reach the peak pressure vacuum or negative pressure, but in fact there is no negative pressure, so the liquid generate a great force, pulling the liquid molecules split into cavities of an empty core. This cavity is very close to a vacuum, it reaches the maximum reverse pressure ultrasonic rupture rupture arising due to the strong impact of the impact surface of the dirt off. This composed of numerous tiny cavitation bubbles rupture and resulting shockwave phenomenon known as “cavitation” phenomenon. ultrasonic cleaning solution is a chemistry liquid that used to assist the ultrasonic cleaner in doing its cleaning job and get a excellent cleaning result.The purpose of the solution is to break the bonds between iterms and their dirt.plain water alone would not normally be effective. The primary purpose of the ultrasonic activity (cavitation) is to assist the solution in doing its job. An ultrasonic cleaning solution contains various ingredients designed to optimize the ultrasonic cleaning process.For example, reduction of surface tension increases cavitation levels, so the solution need to contain a good wetting agent (surfactant). Type 304 is the most versatile and widely used stainless steel. most people still sometimes referred to its old name 18/8 ,because its main chemical components including 18% chromium and 8% nickel. 2.304 has excellent corrosion resistance in a wide variety of environments and when in contact with different corrosive media. 3.it also has good resistance to oxidation in intermittent service up to 870°C and in continuous service to 925°C. Applications: 304 stainless steel is typically used in: Typical chemical composition Typical Physical Properties Typical Mechanical Properties 
Waves can be divided into three types, namely infrasonic, sonic, ultrasonic. Infrasound frequency is below 20Hz; sonic frequency of 20Hz ~ 20kHz; ultrasonic frequency is above 20kHz. Sound waves is the spread form of the object mechanical vibrations state ( or energy ) . Vibration is defined as substances called particle in its equilibrium position near the reciprocating movement form . For example, by percussion drum , it is up and down vibration , the vibration state of the medium to spread in all directions through the air , this is a sound wave.
In addition cleaning medium containing gas and dissolved oxygen has significant influence.
An ultrasonic transducer is a device that converts electric energy into mechanical energy.
It take a signal in one form (electrical) and convert it into a signal of
another form (a sound wave, which also may be expressed as a acoustics pulse or pressure wave).
So,the function of the transducer used in ultrasonic cleaning is to convert the electrical pulses from the generator into a sound wave or pressure wave. When this sound wave/pressure wave is driven through a liquid with appropriate amplitude it will cause the formation of a cavitation vapor/vacuum cavity,which is the scrubbing force found in ultrasonic cleaning systems.
Ultrasonic generators are the power source for providing electrical power to the transducer at the voltage required for operation. Each generator is designed to drive a designated number of transducers.
in general, the ultrasonic cleaning tank is made of sus 304 stainless steelWhat is ultrasoic power?
This blog article will tell you more—-Four steps to tell you what is ultrasonic power and how to choose.
What is ultrasonic cleaning solution?
So i think you should get a good ultrasonic cleaning agent in your cleaning process .it is easy to use, cheap,save time and high efficient.
type sus 304 has many features:
1.its Antirust performance is better than 302 stainless steel materials and have a high temperature resistance.
so,304 sus staninless steel is widely applied in many kinds of fields
